Chapter 97 : Chapter 97 The Laws of Rosh Chodesh and Sanctification of the Moon
§1
Some people are accustomed to fast on Erev Rosh Chodesh and recite the order of
Yom Kippur Kattan, for on this day we are forgiven for all the sins committed in the past month. It is likened to the
Seir [goat offering] of Rosh Chodesh, and as we say in the Mussaf service, "It is a time of atonement for all their generations." Each communifty should follow its own custom.
§2
It is a Mitzvah to have an elaborate meal on Rosh Chodesh, and if it occurs on Shabbos, an extra cooked dish should be prepared in addition to those prepared on other
Shabbasos.
§3
It is permissable to do
Melacha on Rosh Chodesh, but women customarily refrain from doing
melachah on this day. This is a proper custom and it should not be made trivial for them.
§4
Hallel should be said while standing, and without interruption. You should try to say it with the congregation. Therefore, if you arrive at the synagogue when the congregation is about to say
Hallel, you should say
Hallel with the congregation and recite the other prayers later. And if you are saying
Pesukei Dezimrah (that is from
Hodu until after
Az Yashir), you should read Hallel with the congregation without saying the berachah before or after the
Hallel, because the berachah of
Baruch Sheamar and the berachah of
Yishtabach also fulfill the berachah for
Hallel. And only on Rosh Chodesh can this be done, because then parts of the
Hallel are omitted. This is also true for
Chol Hamoed and the last days of
Pesach. But when the entire
Hallel is recited, this cannot be done. And if you recite
Hallel without the congregation, and two [or more] other persons are present, you should say
Hodu in their presence in order that they may respond, for the expression
Hodu (thank Hashem) implies that you are addressing others [to do so]. The law of saying
Hallel in the house of a mourner, may the Merciful save us, is found further in Chapter 207.
§5
After
Hallel the whole Kaddish is recited, a
Seifer Torah is taken out, and four (men) are called (to the Torah). The
kohein reads three
pesukim (verses), which are
Vayedaber, Tzav, Veamarta. The Levi repeats the verse of
V'amarta, and adds:
Es hakkeves echad, veasiris haeifah. The Yisroel reads from
olas tamid until
uverashei chodsheychem. And the fourth person reads from
uverashai chodsheychem.
§6
On Rosh Chodesh it is forbidden to fast and to eulogize someone, and the prayer
Tziduk Hadin is not said.
§7
It is obligatory to sanctify the moon each month. It should not be sanctified until it is definitely night, which is when its light is visible on the ground, so that you can derive some use from its light. If the moon is covered by a cloud, it should not be sanctified unless the cloud is thin and scanty. If you began the berachah, and afterwards it was covered by the cloud, you should complete the berachah. But if you estimate that you will not be able to complete the berachah before it is covered, it is forbidden to begin (the berachah).
§8
The moon must be sanctified only under the heavens (open sky) and not under a roof. If, however, there is no clean place [outside] or because of another situation beyond your control [you cannot go outside]; you may sanctify it inside the house through the window.
§9
It is a mitzvah performed in its excellence to sanctify the moon on
Motzai Shabbos when you are in high spirits and dressed in fine clothes. But if
Motzai Shabbos will occur after ten days from the appearance of the new moon, or if it is feared that you will then be unable to sanctify it, you needn't wait until
Motzai Shabbos. It is a mitzvah to sanctify the moon in the gathering of a multitude of people, since in the multitude of the people is the glory of the King. But it should not be postponed because of this, because the mitzvah to "perform precepts promptly" overrides the mitzvah of "in the multitude of people."
§10
The moon should not be sanctified until the passage of at least three days from the appearance of the new moon, and some wait seven days. And when
Motzai Shabbos occurs before seven days, you should not wait, but you should sanctify it on
Motzai Shabbos. The moon may be sanctified only up to the expiration of half the period of twenty-nine days twelve hours and 793
chalakim (29 days, 12 hours, 793/1080) that is fourteen twenty-four hour days and eighteen hours and twenty two minutes from the appearance of the new moon.
§11
The moon should not be sanctified before
Tisha B'av, and not when one is a mourner, unless his mourning period will not end within the ten full days after the appearance of the new moon. In such a situation, it may be sanctified during the days of mourning. The moon should not be sanctified on a fast day until some food has been eaten. But in any case after Yom Kippur, since we leave the synagogue in a joyous spirit, confident that our sins were forgiven, we sanctify it immediately.
§12
The moon should not be sanctified on Friday night, nor on the night of Yom Tov except in extenuating circumstances, as when by
Motzai Shabbos, the prescribed time will have passed.
§13
A blind person is permitted to sanctify the moon.
§14
If the moon is visible at the beginning of the night, before you began the
Maariv prayer, and there is still time, [i.e., there are still] a few more nights in which to sanctify it, you should say the
Maariv prayer first, and then sanctify the moon, because a mitzvah that is constant takes precedence over one that is only periodic, and also the reading of the
Shemah is a Biblical precept. If, however, there remains only two or three nights [to the end of the period], since the time is short, it may happen that the moon will be covered by clouds. And in the rainy season even if there remain yet four nights [to the end of the period], it may happen that it will become covered by clouds, and therefore you should first sanctify the moon (and then say
Maariv). If the moon becomes visible at the time you are saying
Kerias Shema and its
berachos, and the time is so limited that before you complete
Shemoneh Esrei the time of sanctification will have passed, you may interrupt even in the middle of the
berachos of
Kerias Shema, or in the middle of
Kerias Shema in order to sanctify it. But if possible, you should complete the section [you are reading,] and sanctify the moon between the sections.
§15
If in the month of
Adar (the moon) was not visible until the night of the fourteenth which is the time for the reading of the
Megillah, the moon should be sanctified first and the
Megillah read afterwards. And if it became visible during the reading of the
Megillah, then if there will be time even after the reading is concluded to sanctify the moon, the reading of the
Megillah is not interrupted; but if by the time the
Megillah is concluded, the time for sanctification will pass, and the entire congregation has not yet sanctified the moon, the reading is interrupted for the sanctifying, and afterwards the
Megillah is concluded. But if only one person has not yet sanctified the moon, and if he stops to sanctify it, he will have to finish the
Megillah alone, he must not interrupt, because the public reading of the miracle takes precedence.
